    • A method for self-programming a power nutrunner control system by an initial low speed process for detection and calculation of the screw joint characteristics and by a following adaptation of one or more tightening parameters during a number of succeeding tightening processes, wherein a first preliminary target torque level (MPT) is set as a down shift point from a high speed running down phase to a slow final tightening phase. All tightening processes, the initial screw joint characteristic detecting process included, are performed to a desired final pretension level (MF). After having determined the characteristics of the actual type of screw joint, the rotation speed (v) and the preliminary torque target level (MPT) are stepped up, either with the speed increase first and the preliminary target step up thereafter or both at the same time, until the distance between the obtained angular position ( PHI ) of the joint at the end of the first tightening step and the angular position ( PHI F) obtained at the aimed pretension level (MF) is short enough to provide a satisfactory short overall cycle time for the tightening process without risking overtightening of the joint.
    • 一种用于通过初始低速过程对功率管理器控制系统进行自编程的方法,用于检测和计算螺纹接头特性,并且在许多后续紧固过程中通过以下适配一个或多个紧固参数,其中第一初步目标 转矩水平(MPT)被设置为从高速运行阶段到慢速最终紧固阶段的下降点。 所有的紧固过程,包括的初始螺纹接头特征检测过程都被执行到所需的最终预张力水平(MF)。 在确定了实际螺纹接头类型的特性之后,转速(v)和初速转矩目标水平(MPT)被加以升高 时间,直到在第一紧固步骤结束时获得的接头的角度位置(PHI)与在目标预张力水平(MF)处获得的角位置(PHI F)之间的距离足够短以提供令人满意的短整体 紧固过程的循环时间不会导致接头过紧。
